摘要： A large-size circulating fluidized bed boiler, comprising: a furnace having a vertical furnace center line; and at least two groups of cyclones, each cyclone of each group of cyclones having an inlet gas pass communicated with the furnace. A furnace cross section formed by outer sidewalls and located at the inlet gas pass of the cyclone is a polygon having 2×n sides, and n is a positive integer greater than 1. The polygon is axially symmetric with respect to a perpendicular bisector of each side of the polygon, and when n is 2, the polygon is a square. Triangles formed by two endpoints of an inlet of the inlet gas pass of each cyclone at the cross section and an intersection of the furnace center line and the cross section are congruent. A single flow field in communication with each of the inlet is formed in the cross section.

摘要： Water-cooling U-valve is composed of a downcomer (1), a riser (2), and a return chute (3), which are sequentially connected. An intermediate partition (4) is disposed between the downcomer (1) and the riser (2), the lower parts of which are interconnected. A material returning partition (5) is disposed between the riser (2) and the return chute (3), the upper parts of which are interconnected. The casing of U-valve is membrane walls, the inside of which are laid with refractory. Some water-cooling tubes of the membrane walls extend into the inside of the U-valve, forming the water cooing intermediate partition (4) and material returning partition (5). There are headers (40, 50) for both the intermediate partition (4) and the material returning partition (5), and the headers (40, 50) are connected with the headers (33, 13) formed by some water-cooling tubes of membrane walls by connecting tubes (7, 8). The invented U-valve can guarantee that there is no expansion difference between the partitions and the casing, which can extend the working life of the partitions and realize the long-term safe and stable operation of the U-valve.
